Mo3.4-V1.0-Cr7-Co5 is a high-speed tool steel (HSS) variant with elevated molybdenum, chromium, and cobalt content, designed for demanding cutting and forming applications. This composition combines exceptional hardness from high carbon and vanadium content with cobalt's heat resistance, making it suitable for high-temperature machining operations where tool life and wear resistance are critical. Compared to standard M-series tool steels, the increased molybdenum and cobalt boost thermal fatigue resistance and cutting speed capability, particularly for interrupted cuts and abrasive materials.
